Yilning turli fasllarida dorivor o'simliklarda biologik faol moddalarni aniqlash




Annotatsiya:Turli xil o'simliklarda  masalan, qora tutun (Morus nigra L.), shaftoli (Prunus persica L.), gilos (Serasus vulgaris L.), uzum (Vitis vinifera) va yunoncha yong'oq (Juglans regia L.) turli mavsumlarda biologik faol moddalar umumiy miqdori aniqlanadi - antioksidantlar, flavonoidlar va C vitamini. Natijalar antioksidantlarning eng yuqori konsentratsiyasi bahorda yong'oq va shaftoli davrida yoz mavsumiga qaraganda topilganligini ko'rsatdi. Yong'oq barglarida antioksidantlar miqdori taxminan 9.105 ± 0.05 mg / g, shaftoli barglarida esa 9.082 ± 0.075 mg / g atrofida edi.

1. Introduction

Antioxidants are biologically active compounds and are important in plant and animal organisms. Antioxidants are essential for the function of natural detoxification systems to remove free radicals and radical forms from the body. Free radicals would arise as a result of chronic stress and the accumulation of radioactive, various chemicals in the environment in the body [1, p. 34–36;  2, p. 556 ]. Flavonoids are only synthesized in plants and have important biological significance in the human body. The herbivorous nature of row plants depends on flavonoids, which depends on the growth of plants. Flavonoids cause a variety of disorders in the body. Many flavonoids improve the elasticity of the vascular wall and control their permeability. Flavonoids of some plants also have the properties of herbivores and urine.

2. Results and discussion.

The main purpose of our work is to determine the amount of Flavanophytes in the leaves of fruit trees. Therefore, we have determined the amount of flavonoids in different seasons in the leaves of fruit-bearing trees, such as shotut, peach, nuts, which have the medicinal properties(Table 1).

As you know, vitamins - Vitamin C, which is the most antioxidant feature. Vitamin C improves blood circulation in the body, normalizes cholesterol.

In this regard, we aimed at determining the amount of vitamin C in the spring, summer, and cats and the activity of the ascorbic acid oxidase enzyme in the leaves of the plants showing antioxidant properties.

Our findings show that the amount of ascorbic acid in the foliage, peach, and walnut leaf plants that have antioxidant properties has been found to be relatively higher than in the summer. That is, the leaves of the shotut are 140.8 mg%, 79.2% of peach leaf, 52.8% in walnut leaf (Table 2).

As you know, the negative effects of environmental factors and applying of the pesticides in agriculture will cause as harm to the health of the population. The human body accepts residual pesticides through the nutritional chain. It gradually begins to accumulate in different organs, especially in the liver. As a result, the metabolism in the cells changes and causes the gradual formation of various free radicals. Our department has been studying the effects of karate pesticides on rats during many years and ways of their correction have been studying [1, p. 34–36; 3, p. 93–96; 5, p. 172–174]. Plant antioxidant used in correction. The main purpose of our work is to find cheap and suitable natural antioxidants. Therefore, we detected the total antioxidant quantity in the plant antioxidant

factor by Rogojin method [4, p.254]. In the correction the plant antioxidant factor (PAF) was applied from extracted 3 different fruit trees of leaves in Morus nigra L., Prunus persica L., Juglans regia L. and positive results were obtained. Therefore, we researched the total amount of antioxidants in a number of fruit trees. The results were shown in (Table 3).
